About the 872 Area Code

Area code 872 is the overlay for the 312 code, covering downtown Chicago and its dense urban neighborhoods. As Chicago's urban core has grown more populated and tech-forward, the 312 code's capacity has been supplemented by 872. Both codes now serve the same geography and require 10-digit dialing within the area.
